| Abstract: | The improvement of the synthesis of P507 solvent impregnated resins,and the performance of adsorption and separation of Zr(Ⅵ) and Hf(Ⅵ) in H2SO4 by these resins were performed.The adsorption of Zr(Ⅵ) and Hf(Ⅵ) has been carried out in the different acidity and temperature and separation coefficients were obtained.The optimum time of adsorption equilibrium was studied and the separation coefficients in the conditions of various percentage content Hf(Ⅵ) and the elution facts of Zr(Ⅵ) and Hf(Ⅵ) were done. |
